We have athe high/low chair from toys r us which is currently on its lowest setting because DS can get out of it even if he is strapped in. Paranoid that he will take a tumble and wondering if anyone had any suggestions, have drawn a blank and i am loathe to get another high chair at this stage as he will be out of it soon if we follow DS1(he was in a booster type seat from about 18 months)
